Just keep on trying till you run out of cake

I have a theory about polls and comments. See, I always seem to get more comments when I do a poll than otherwise. People feel compelled towards the clickiness of the poll, and then discover that none of the options quite fit, and feel compelled to comment with an accurate representation of their view. Whereas if I just ask for comments, moswt people cannot be bothered. So, a poll to see if my intuition on this is correct.
